如何将数据库字段绑定到ASP.NET 2.0中的HTML TITLE元素？

I know how to do this in MVC:

我知道如何在MVC中这样做:

<title> <%= Model.Title %> </title>

I also know how to bind a SQLDataSource or ObjectDataSource to a control on a form or listview.

我也知道如何将SQLDataSource或ObjectDataSource绑定到窗体或列表视图上的控件。

But how do I render a field from my SQLDataSource or ObjectDataSource directly into the HTML?

但是如何将我的SQLDataSource或ObjectDataSource中的字段直接呈现到HTML中?

3 个解决方案

#1

You can declare a property and set its value using your desired field's value.

您可以使用所需字段的值声明属性并设置其值。

Code-behind:

private string myTitle;
protected string MyTitle
{
   get { return myTitle; }
   set { myTitle = value; }
}
protected void Page_Load(object sender, EventArgs e)
{
    MyTitle = "Testing 123!";
}

Markup: <title><%= MyTitle %></title>

标记:

<%= MyTitle%> </ title></p>

#2

You can use the Page.Title property to set the title in code behind.

您可以使用Page.Title属性在后面的代码中设置标题。

Once you've run your SelectCommand or equivalent on your data source, just simply assign Page.Title a value from the result set.

在数据源上运行SelectCommand或等效命令后,只需简单地分配Page.Title结果集中的值即可。

Alternately, you can use the aspx page itself, and just inside the html assign a text string, like this:

或者,您可以使用aspx页面本身,并在html内部分配一个文本字符串,如下所示:

<title>
  <%= dataSource.Select(...) %>
</title>

#3

In WebForms you still need to use a WebControl that implements DataBinding as the "container" for your fields. For instance, a GridView, Repeater, ListView, FormView or DetailsView. Unfortunately there isn't a WebControl designed specifically for rending just one row or object. So, you have a choice:

在WebForms中,您仍然需要使用实现DataBinding的WebControl作为字段的“容器”。例如,GridView,Repeater,ListView,FormView或DetailsView。遗憾的是,没有一个专门用于仅仅渲染一行或一个对象的WebControl。所以,你有一个选择:

Use a Repeater something like this:

使用这样的Repeater:

<asp:Repeater ID="Repeater1" runat="server" DataSourceID="MyDataSource">
        <ItemTemplate>
            <%# Eval("MyProperty") %>
        </ItemTemplate>
    </asp:Repeater>

Another alernative is to not use a DataSource. Instead, add properties to your page and then bind your data to these. For example, in your page codebehind:

另一个问题是不使用DataSource。而是向页面添加属性,然后将数据绑定到这些属性。例如,在您的页面代码隐藏中:

public string MyPageProperty 
{
    get { return _myPageProperty; }
    set { _myPageProperty = value; }
}

protected void Page_Load(object sender, EventArgs e)
{
    MyPageProperty = "This is some data";
}

You can then do this in your page:

然后,您可以在页面中执行此操作:

<div>The value is: <%= MyPageProperty %></div>

Hope that helps.
